Managing license keys
Accessing software functionality for your storage system requires a license key.
Overview
When you install a license key, it is automatically enabled and the timer on the license starts at that time. To preserve time on a term key license, you can disable it without uninstalling it. When you need the software, enable the license again.
If you do not install the software before you install the license key software, the software will install correctly but will be disabled. To enable a license key, install the prerequisite software, and then enable the key.
License key types
To use software, you must install the license key provided when you purchase that software.
You can use software with licensed capacity for a term key by installing a term key and overwriting a permanent key as long as the term key is valid. If the term key expires when the system is being used, and the capacity needed for the operation is insufficient, operations that you can perform are limited. In this case, a SIM that indicates the term key expiration (reference code 7ff7xx) is output on the Alerts tab in the Storage Systems window.

Using the permanent key
You can purchase the permanent key to use a software application indefinitely. You must estimate a licensed capacity required for using the software application and purchase a license key for the amount of the required capacity.
- If insufficient license capacity is installed, Not Enough License displays in the status field of the License Keys window, and the software application is not enabled.
- If the capacity of the usable volume exceeds the licensed capacity while the storage system is running (for example, when an LDEV is additionally installed), Grace Period displays in the status field of the License Keys window. You can continue to perform the same operations, but the deficient amount of license capacity must be purchased within 30 days.
Using the term key
You can purchase the term key to use the software application for a specific number of days. You must estimate a licensed capacity required for using the software application and purchase a license key for the amount of the required capacity.
- If insufficient license capacity is installed, Not Enough License or Grace Period displays in the status field of the License Keys window.
- You can enable or disable the term key for each software application. Unlike the temporary key and the emergency key, the number of days the term key is enabled is counted as the number of effective days of the term key rather than the number of elapsed days from the installation date.
- The number of effective days is decremented by one day when the date changes.
For example, if the term key is set to be enabled for 150 days during installation and the term key is disabled for 100 days and a total of 250 days have elapsed since the installation, the number of remaining effective days of the term key is 215 days. This is determined by subtracting 150 days from 365 days. By disabling the term key on the days when the software application is not used, you can prevent the unnecessary shortening of the period in which the term key can be used.
- If the term key is expired, Not Installed displays in the status field of the License Keys window, and the software application is disabled.
Using the temporary key
You can use the temporary key for trial purposes. The effective term is 120 days from the time of installation of the temporary key. The effective term is not increased even if the temporary key is reinstalled during the effective term.
If you uninstall the temporary key, even though the effective term remains, Temporary is displayed in the status field, Not Installed is displayed in the Key Type field, and the remaining days of the effective term are displayed in the Term (Days) field of the License Keys window.
If the temporary key expires, you cannot reinstall the temporary key for 180 days. Expired displays in the status field of the License Keys window, and the software application is disabled.
Using the emergency key
You can use the emergency key if the license key cannot be purchased, or if an emergency occurs, such as a system failure or a communication error.
You can also use the emergency key if the configuration of the software application that is installed by the temporary key remains in the changed status and cannot be restored to the original status. For example, if you do not plan to purchase the software application after using the temporary key for trial purposes, you can restore the changed configuration to the original status by temporarily enabling the software application with the emergency key.
- If an emergency key is installed for a software application for which a permanent or term key is installed, the effective term of the license key is 30 days. However, because the emergency key can be reinstalled during the effective term, the effective term can be restored to 30 days.
- In other scenarios, the emergency key can be installed only once.
Cautions on license capacities in license-related windows
License capacities are displayed not only in license-related windows but also in the Pools window and the Replication window.
When you install or overwrite a temporary key or an emergency key for an installed software application, the license capacity before the overwrite installation is displayed as Permitted (TB) in license-related windows. However, Unlimited (license capacity for the temporary key or emergency key) is displayed as Licensed Capacity in the Pools window and the Replication window.
For example: You install a term key that has a license capacity of 5 TB for Compatible FlashCopy®, and when the term expires, you use an emergency key. In license-related windows, 5 TB is displayed in the Permitted (TB) field. However, in the Licensed Capacity field in a Replication window, Unlimited (capacity of the emergency key) is displayed.
Estimating licensed capacity
The licensed capacity is volume capacity that you are licensed to use with the software application. You must estimate the amount of capacity that you want to use with the software application before you purchase the permanent key or the term key.
Software and licensed capacity
The following table describes the three types of licensed capacity: used capacity, mounted capacity, and unlimited capacity. The type you select depends on the software application.
Type | Description |
Used capacity | The licensed capacity is calculated by using one of the following capacities:
If the pool contains pool volumes that belong in accelerated compression-enabled parity groups, you must purchase physical capacity of the pool for the license capacity. |
Mounted capacity /usable capacity | The licensed capacity is estimated by using the capacity of all the volumes in the storage system. When you estimate for the capacity of the accelerated compression-enabled parity groups, the physical capacity of the parity group is the maximum of the estimated capacity, even if you created an internal volume which exceeds the physical capacity of the accelerated compression-enabled parity group. See the Provisioning Guide for an explanation of accelerated compression. |
Unlimited capacity | You can use the software regardless of the volume capacity. |
The following tables list the software bundles and specify the licensed capacity type(s) for each bundle.
Software bundle | Licensed capacity |
Base Package | Used capacity or mounted capacity |
Advanced Package | Used capacity or mounted capacity |
Remote Data Protection | Used capacity or mounted capacity |
Global-active device | Used capacity or mounted capacity |
Software bundle | VSP G350, G370 | VSP G700, G900 | VSP F350, F370, F700, F900 |
Hitachi Foundation Suite | Unlimited | Used capacity or mounted capacity | Unlimited |
Hitachi Remote Data Protection | Unlimited | Used capacity or mounted capacity | Unlimited |
Global-active device | Unlimited | Used capacity or mounted capacity | Unlimited |
Hitachi Encryption License Key | Unlimited | Unlimited | Unlimited |
Calculating licensed capacity for a normal volume
A normal volume is a volume that is not blocked or protected. For OPEN-V volumes, the licensed capacity of a volume is the same as the capacity specified when creating the volume.
Calculating licensed capacity for an external volume
Use the following equation to calculate the licensed capacity for an external volume:
External Volume Capacity (KB) = Volume Capacity (number of blocks) X 512 (bytes) / 1,024
Calculating pool capacity
The license capacity of Dynamic Provisioning is calculated using the total capacity of the Dynamic Provisioning pool. If you use Dynamic Provisioning V-VOLs as P-VOLs or S-VOLs of ShadowImage, TrueCopy, Universal Replicator, or global-active device, the license capacity of ShadowImage, TrueCopy, Universal Replicator, or global-active device is calculated by using the page capacity allocated to the Dynamic Provisioning V-VOLs (that is, used pool capacity).
For more information on calculating pool capacity, see the Provisioning Guide.
Accelerated compression-enabled parity group capacity
For the actual capacity of accelerated compression-enabled parity groups, the total capacity of LDEVs created in the parity group and the physical capacity are compared. The one with the least capacity is added as the actual capacity. See the following table for an example.
Total LDEV capacity in the parity group | Physical capacity | Actual capacity which is added |
12 TB | 20 TB | 12 TB |
24 TB | 20 TB | 20 TB |

License key expiration
If the license key for software-A expires, the license key for software-B is also disabled if software-B requires an enabled software-A. In this scenario, Installed (Disabled) is shown for software-B in the Status column of the License Keys table. After that, when you re-enable software-A, software-B is also re-enabled. If the Status column for software-B continues to display Installed (Disabled), go to the License Keys table and manually change the status of software-B back to Installed.
After your license key expires, no new configuration settings can be made, and no monitoring functions can be used with Performance Monitor. Configuration settings made before the expiration of the license key remain in effect. You can cancel configuration changes for some software.
